Datsun Roadster Forum-311s.org

I just purchased a sr20de s15 from ebay ($1300) . looks like I will not make it to Solvang this year. The shipment arrived 5 days prior to their original promise date. I inspected the engine and trans and it truly looks like a 50k motor as described by the seller. I did a compression test and 195psi all around. This will be a interesting journey as this is my first sr20 swap plus I'm trying to keep the budget at 3k.

I need recommendations on: "at least for now"
What exhaust manifold to use ?
also where I can purchase a engine harness ? or if i should use the one they supplied? (it is in perfect condition)

Thanks in advance

I can't answer your questions, but I'll be following your build- and your budget. Did you get another car, or is it going into the white one?

Good for you Shant, another EFI roadster. Kevins the guru around these parts that has all the answers.

Looks like fun, was a real tough decision between that motor and the busa. One thing is for sure, if my busa experiment doesn't pan out like I want, that's what going in.

SR20 engine swaps are overrated!
Shant I'm excited please post this in the engine swap section so we can follow your journey!

@JohnnyMac this is going into my white car
@alvin I sure will

Subscribed, though of no help technically!

Shant I am almost finished with my s15 de swap . For the exhaust manifold i used fwd sr20 , g20 . The s15 harness is difficult not a lot of info on pinouts . Wiring specialty's is making my harness, yury can hook you up with there pro harness .I have some 1 3/8 tube for water neck left over ,pm me u can have it . I only have a few thing and im ready to fire up . Being on east coast my sources are limited so i did almost every thing my self keep cost down and not cutting cutting corner on a safe and reliable swap ,Im it it for about 4800 bucks .It was alot of work and i had a fun doing it .If you have access to a plasma cutter it definitely will make it easier . Good luck with your swap .

Shant,

Congrats on your engine-- we can provide you with an already converted (ie. EGR port welded up) FWD SR20DE exhaust manifold-- though with your wrecking yard connections, you can easily find one yourself!

I do have laser cut exhaust flanges that I can sell you-- which will make fabricating the down pipe easier!

Talk to you soon,

Michael

@Michael thank you ... I will be contacting you soon with a list of parts that I need

Say what?

I couldn't find a build thread anywhere. Did it get started? It would be nice to see how close it stays to budget. I assume this is engine only and no brake, rearend, or suspension upgrades.

update on my swap

installed the body on to the frame. I also installed the engine and trans to ensure fitment.

also add $300 for miscellaneous parts

I still need to purchase
